Abstractor Notes

(This code is effective for cases diagnosed 2021 and later. For cases diagnosed prior to 2021 see code: 9861/3.)

Patients usually present with lower hemoglobin and lactate dehydrogenase levels and lower white blood cell and peripheral blood blast cell counts.

Cases with a history of prior therapy (in particular radiation therapy), MDS, or a myelodysplastic/myeloproliferative neoplasm may harbor RUNX1 mutations, but are excluded from this category.

Diagnostic Confirmation

This AML is part of the "AML with recurrent genetic abnormalities" group. Since this AML is diagnosed based on genetics, diagnostic confirmation will always be 3.

Definition

Acute myeloid leukemia (AML) with mutated RUNX1 is a de novo leukemia with greater than or equal to 20% bone marrow or peripheral blood blasts cells that may have morphological features of most AML, NOS categories and has a higher frequency among cases with minimal differentiation.

Definitive Diagnostic Methods

Bone marrow biopsy
Genetic testing
Immunophenotyping
Karyotyping

Genetics Data

ASXL1
FLT3-ITD
IDH1R132
Karyotypic abnormalities, most commonly trisomies 8 and 13
KMT2A
Mutated RUNX1

Immunophenotyping

CD13+ (expression/positive)
CD33+ (expression/positive)
CD34+ (expression/positive)
HLA-DR+ (expression/positive)
MPO+ (expression/positive)

Treatments

Hematologic Transplant and/or Endocrine Procedures
